1 To-aZZ whom-it may concern."

Be itknown that I, AUGUsT G.- LInB nANN, aj-citizen of the United States, residing at wGh-i'cago, in the county of Cook and State of Illinois, have invented certain new and usefulIrnprovements in Fastening Devices for of which the following is a to railway track form 'of fastening for holding rails in posij tion on rail chairs and the like. l The principal object of the invention 1s to provide a fastening which maybereadily inserted Within and Withdrawn from the upper side of a cross tie and which 1s positive in its action and does not depend upon the friction ofjthe woodfibers of the tie to hold said fastening in position thereon. 2O

A further object is to provide a fastening device-including abolt and socket member "having interengaging' parts whereby, when 1 he boltisinserted within the socket member and givena'partial turn, saidbolt will b to so position thefastener within the cross tie that the anchoring end thereof will be damageand corrosion.

held against vertical displacement.

A still-further object of the invention is spaced upwardlyfrom the lower side of the tie and thus be housed and protected from A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efliciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, portions and minor details of construction maybe resorted to within the scope of the appended claims. v

In the drawings:

Figure 1 is a perspective view of a rail chair, showing my improved fastening de' .vice;

Fig. 2 is a longitudinal sectional view;

Fig. 3 is a horizontal sectional view taken on the line 33 ofFig. 2 and looking in the direction of the arrows.

-to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, -A represents the rail having a standard cross section, and B the tie supporting the rail. Mounted as shown. vided with a series of horizontally disposed is provided withupstand ing abutment's' 6 and ispierced by c-op'enings 7 for the-recepably in the "form of screw spikes which serve to permanentlysecure thebed plate to the upper-surfaceof the cross tie, as shown.

Arranged opposite-each primary fastening 'tion' of primary fastening devices 8, preferdevice 8' is an auxiliary fastening deviee9,

preferably in the form ofa bolt,- the upper "end of which is threaded at '10 and passes througha 'rai-l clampingmember 11, there being a nut 12 engaging thethreads on the bolt 9 and adapted to bear. against the rail V clamping memberll for holding thelatter securely in engagement with the-base flange oi' the rail. The upperend ofeach*bolt 9 is curved or rounded at 1*3 wh 1Iethe=lowerend," thereof is reduced to form a cylindrical exr tension 14 which fits within a socketmem her 15. The socket member 15 is preferably cylindrical in shape and; provided with spaced 'V-shaped anchoring ribs 16 adapted to engage the fibers of the wood off'which the 2 tie is formedwhen said socket member is positionedwithin the -tie,'there being-an opening 17- formed in the bottomofthe tie and adapted to receive the socket member, The socket member-15' is-prosegmental lugs 18, the end faces of which are spaced apart to form recesses 19 adapted to receive radiating lugs 20 formed on the extension 14 of the bolt 9; The upper facesof the radiating lugs 20' are preferably curved or beveled, although said faces may be fiat or square, if desired. The inner wall of the tubular socket member 15 is formed with a plurality of stop ribs 21, one rib being preferably arranged opposite each segmental lug 18, the purpose of said ribs being to limit the rotary movement of the bolt 9 with respect tothe socket member, as will be more fully explained hereinafter.

It will thus be seen that by causing the lugs 20 to register with the openings 19, the

bolt may be lowered within the socket until the cylindrical extension 14: reaches a' point near the bottom of the socket when, by giving the bolt 9 a partial rotation in either direction, the lugs '20" will ride over the faces of the segmental lugs 18, andengage the. stop ribs 21, thus preventin further rotary movement of the bolt 9 an 1 securely anchoring the lower end of the bolt within the cross tie. In order to remove the bolt 9 to facilitate rail renewals or to replace the bolt when broken or damaged, it is merely necessary to loosen the nut 12 and partially thebolt 9 is inserted within the socket mem- A her, said bolt may be locked by rotating the same in either direction. It will also be noted that the lower face of the socket member 15 is spaced upwardly from the lower side ofthe cross tie, thus effectually protecting the anchoring end of the bolt from damage and corrosion- It will thus be seen that should the bolt 9 need replacing, for any .reason, it is not necessary to remove the tie from the ballast and invert said tie, in order to remove thebolt, as is the case where the heads of the bolts bear against the bottom of the tie, it being merely necessary to loosen the nut and give the bolt a partial rotation in order to effect the removal thereof, as before stated.

. Havin thus described the invention, what is claime as new is: 7

1. The combination with a cross tie and chair, of a socket member embedded in the cross tie and having its inner wall provided 1 with a circumferential row of spaced in- -wardlyextending lugs, a fastening device having its lower end reduced and provided with radiatinglugs co-acting with the lugs on the socket member for holding the fastening" device against vertical displacement,

and a rail clamping member carried by the with radiating lugs co-acting with the lugson the socket member andadapted to bear against the ribs. for limiting the rotary movement of the fastening device, and a rail clamping member carried by the fastening device.

3. A fasteningdevice forrail chairs din-- eluding a socket memberhaving external anchoring ribs and internal stop ribs,.and a bolt insertible within the socket member; and

provided with lugs adapted to bear against;

the stop ribs.

4:. A fastening device for rail chairs including a socket member having internal horizontal lugs and vertical stop ribs arranged adjacent said lugs, and a bolt having its upper end threaded and its lower end reduced to form an extensionprovidedwith radiating lugs movable over the surface of the lugs on the socket member and into engagement with the stop ribs.

5. A fastening device for rail chairs in- I eluding a socket member having internal stop ribs, and a bolt provided with lugs adapted to bear against the stop ribs when said bolt is inserted within the socket member and rotated in either direction;

In testimony whereof I aflixmy signature. 7
